Meh a Lot of u M4.3 people use M43 because of the smaller size of the cameras AND the lenses. My EM-1 with the 12-40 2.8 lens weighs less than most full flame 24-70 2.8 lenses alone. I think Olympus and Panasonic will continue to have a market for micro four thirds. This sony willdefinately take the market away from Canon/Nikon who no longer have an excuse for not having a mirror less camera in the market.

May be 20MP with 4/3 size ,it should undoubtedly outperform sony rx100 mark3 sensor (In term of resolution and Image Quality)

Do you really want to get into a Megapixel battle on a Photography website. If your benchmark is megapixels then the new Canon must be a useless camera since it only has 20Megapixels compared to 36 for the Nikon.
